SKYLIGHT.

SPECIFICATION forming part of Letters- Patent No. 244,711, dated July 19, 1881.

Y Application filed April 27, 1881. V (No model.)

To all whom it may concern Be it knownthat we, FRANK M. CAMPBELL and ANTHONY C. DUNLEVY, of St. Louis, in the county of St. Louis and State of Missouri,

have invented new and useful ImprovementsV November, 1877.

For illustrating the improved skylight reference will be had to the annexed drawings, making a part of this specification, in which- Fi-gure 1 is a vertical. 4transverse section of the bars and glass of the improved skylight. Fig. 2 is a perspective view ot' a sash-bar.

Like letters of reference refer to like parts in the several views.

That a full understanding ofthe nature and importance of the improvement over said patent may be had, a brief description of the patented sky-light alluded to will be made.

In the above said patented skylight each bar of the sash consisted of a single piece of sheet metal, so bent as to form a central web of the bar, and two gutters, one on each side of the web; also, two stiffeninganges at the lower edge of the web, one along each side thereof. The edges .of the gutters served as supports for the plates of glass, which are laid thereon so that the edges may project over the gutters that the drippings from the glass mayfall therein. Over the edges of the plates of glass, and also over the. bars, are placed caps or. hoods drawn tightly down upon the glass by clamps. The longitudinal and transverse bars are made alike, and are connected toV each other by adjusting the parts of the one to the corresponding-parts of the other, which are then united by soldering.

In practice it is found to be too much labor and requiring too much lskill to make the bars with two gutters and two stidening-anges and fit them together to form the sash, hence the sash is expensive. It is also found that the rain and melting snow sometimes drifts in under the caps or hoods, and as it drips from the edge of the glass into the gutters more or less of it runs along back under the glass by capillary attraction, and makes its way between the edge of thegutters and the glass, and falls therefrom to the inside of the building. To

vavoid these defectsin the skylight the bars of tween the edges of the glass and the web, as

seen in Fig. 1, and indicated by the dotted lines in Fig. 2. spread outward so far as to press against the lower corner of the edge of the glass.

The apron may be kept distended, so as to be in'contact with the glass by a spreader, which may consist ofv a rod, (not shown in the drawings,) extending along the under side of the apron near its line of contact with Vthe glass. Said rod should be attached to the side of the web by one or more springs, so adjusted that the resiliency of said springs will keep the apron in contact with the glass.

The apron may consist of rubber-cloth, tarred paper, asbestus-cloth, or of felt, or other brons material, and may be kept in contact with the edges of the glass by the means before mentioned, or any suitable means, the elasticity of the material suflicing when `it possesses that quality. Felt is, however, preferred, as its loose fibrous quality will enable it to absorb the water more readily that may drip from the glass, and conduct ittherefrom into the gutters by capillary attraction and gravity, instead of passing along the under side of the glass and dripping into the space below.

Over the edges of the plates of glass and the apron are placed caps or hoods G, the edgesl of which rest upon4 the glass, and are secured in place with clamps H, substantially in the same manner as shown in the patent of Novem- The sides of the apron depend and IOO ber 6, 1877, above referred to. The space below the cap is filled with a packing of some fibrous or occulent material, as shown in the drawings at N.

From the above it will be obvious that in constructing the bars of the sash without stifening-flanges, they are consequently more simple in structure, and therefore can be made with less labor, skill, and of less material, hence they are less expensive; and, furthermore, by virtue of the simple form of the bars the longitudinal and transverse bars can be more easily and readily adjusted to and joined to each other than when the said bars are made with stiifening-langes, and are equally secure and sufficiently strong.

The effect of the apron above described, by its contactwith the edge of the glass, prevents the water that may find its way in under the hood from flowing back by capillary attraction along the under side of the glass, diverts it downward into the gutters, and prevents it from leaking into the building, as aforesaid.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In combination with the sash-bar, consisting of one piece of sheet metal and provided with gutters B and C, central compact web, cap G, packing inserted in the space below the cap, and an apron hung upon the ridge of the web of the sash-bar and depending therefrom between the said web and edges of the glass into the gutters, substantially as described, and for the purpose set forth.

3. In skylights, the gutters B and C, with a web extending lengthwise through the said gutters,with the glass plates on thesides thereof resting upon the edges of the gutters, in cornbination with an apron, F, arranged between the edges of said glass within the gutters, substantially as described, and for the purpose set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
